New Electric Vehicle Battery Technology Claims to Increase Fuel Savings
Johnson Controls, the maker of VARTA automotive batteries, has unveilled its first-generation 48-volt Lithium-ion Micro Hybrid battery.
“We expect this technology to play an integral role in meeting aggressive fuel economy and emission reduction targets,” says Ray Shemanski, vice president and general manager of the Original Equipment Group for Johnson Controls Power Solutions.
Featuring a dual voltage architecture, Johnson Controls Micro Hybrid battery system will involve a 12-volt starter battery and a 48-volt Lithium-ion battery that enables improved energy generation and consumption. Johnson Controls’ engineers claim this technology has the potential to provide up to 15 percent fuel savings in vehicles and will be made available for testing with key automotive customers from December onwards.
“Micro Hybrid systems will be able to support the automotive industry’s needs at a much lower cost than hybrid or electric vehicles, and therefore, offer a mass-production solution that can be leveraged across our customers’ fleets,” said Shemanski.
The 48-volt battery is designed with the capacity to quickly capture energy from braking and can support higher loads such as air-conditioning and active chassis technologies. The 12-volt battery will continue to provide power to the vehicle starter, interior and exterior lights, and entertainment systems such as radios and DVD players.
The prismatic Lithium-ion cells and complete systems for the Micro Hybrid battery prototypes will be made at Johnson Controls manufacturing facility in Holland, Michigan. The battery is designed with standardised components and size to help drive scale and minimise cost.
“We expect that Micro Hybrid technology will be adopted in Europe first, due to more stringent fuel economy and emissions standards, and then quickly move to U.S. markets in the next few years with global adoption starting in 2020,” said Shemanski.
